If you’re planning a trip to Iceland and looking for a one-of-a-kind adventure, a snorkeling tour in Silfra Fissure might just be the highlight of your visit. This experience offers a rare peek at the Earth’s crust as you float between the Eurasian and North American tectonic plates—a pretty surreal setting that’s hard to match anywhere else.
While we haven’t personally done this tour, based on countless reviews and detailed descriptions, it’s clear that this experience combines spectacular scenery, expert guidance, and excellent value. Two things that come up repeatedly are the crystal-clear waters—which make you feel like you’re floating in pure glass—and the knowledgeable guides who make the experience both safe and informative.
That said, it’s not necessarily for everyone. The water is cold, and you need to be comfortable swimming or at least confident in water. Plus, the activity is limited to those over 12 years old and with certain physical requirements. If you love nature, geology, or just want a story to tell, it’s likely a perfect fit.
It was great. Super cool experience and something I’ve never done before. The made sure our suits were secure and gave us great instruction. Only thing is I wish they gave us more pictures we paid $20 for like only 2 photos. Use NOTYOTYPICALGAL5 for 5% off.
Filip was the most amazing guide and the whole experience was incredible
This was an amazing experience shared with my daughter. We were fortunate to have a beautiful sunny day which made the time getting togged up outside more comfortable. Our guide, Elsa, was very professional but fun! Our thermal baselayers and the drysuit kept us warm and dry and it was only our faces that felt cold during the snorkeling. The water is crystal clear and there is plenty of time to see the rock formations. Elsa took lots of photos which we purchased. The heated van, hot drinks and biscuits were very welcome at the end of the experience. Thank you!
This tour suits travelers wanting an active, scenic, and educational activity, especially those who enjoy unique geological sights and don’t mind a bit of cold water. It’s a great choice for curious explorers and adventure buffs eager for a photo-worthy experience in the land of fire and ice.

The Experience: What Really Matters
Many reviews mention how the experience feels almost like flying—you’re floating in water so clear that the underwater landscape looks surreal. Several travelers loved the visual spectacle of the tectonic plates drifting apart right in front of their eyes. One review describes a visit to the Silfra Cathedral at 23 meters depth, where you feel like you’re soaring over giant boulders and glittering silt.

More Great Tours NearbyGuides and Customer Service
The guides are often praised for their knowledge, friendliness, and patience. Melissa, for example, called her guide outstanding, emphasizing the customer service aspect. Carmen appreciated how her guide Henry made everyone feel at ease, and Olga highlighted how her guide Konrad was both funny and informative.
An unforgettable experience. Swimming between tectonic plates and through the crevices felt completely surreal. Elsa and Nicolas were amazing — so informative, engaging, and hands on, especially helping us with the dry suits. And the underwater photos they took were such a special bonus.
Such an amazing experience! Quim was our instructor and he was so nice and funny! It was my birthday and he’s saying happy birthday while we had hot chocolate and cookies and was very attentive in the water. I never snorkel before so I started out a little rough, but he helped me a lot. If you were going on the tour bring a lot of socks that’s what gets really cold -not an activity for someone who is claustrophobic or water phobic they put multiple layers on you and it’s hard to adjust anything because the gloves you get strapped into are hard to move around in. It was such a great experience and would 1000% recommend doing.!!
Loved, loved, loved snorkeling. I got out and wanted to go again. My guide was Niko and he was great. The only part of me that was cold was a little bit of my face. Highly recommend.
Good guides don’t just lead—you get insights into the geological process, safety tips, and plenty of photo opportunities. Many reviews mention how guides took the time to make sure everyone was comfortable and even helped with photos, which is a lovely bonus.
Value and Practical Considerations
At $146 per person, this tour is a solid investment for what you get. The scenery alone justifies the price, and the equipment and guidance are top-notch. Plus, the fact that no certification is needed makes it accessible—anyone comfortable in water and over 12 can join in.
However, some reviewers point out that the gear-up process on land can be a bit cumbersome, especially in the cold. Bringing layers, socks, and contact lenses (if you wear glasses) is recommended.
Who Should Consider This Tour?
This isn’t a casual dip in the pool. It’s an active, cold-water adventure that requires a basic level of comfort in water. It's ideal for curious travelers, geology enthusiasts, and those craving a story they'll tell for years. Not suitable for pregnant women, children under 12, or those with certain health issues, but if you meet the criteria, you’re in for a memorable experience.
Final Thoughts: Is It Worth It?

Absolutely, if you’re after a unique, scenic, and educational experience that many travelers say is worth every penny. The combination of crystal-clear waters, geological marvels, and expert guides creates a powerful memory. It’s not just about snorkeling; it’s about standing at a moment where the Earth’s crust is visibly pulling apart beneath you, a sight few will ever see.
The consistent praise about the professionalism of guides and the stunning environment makes this a strong choice for those seeking adventure with a learning twist. Just remember to dress warmly, be comfortable in water, and get ready for a trip that’s as much about the scenery as it is about the sense of wonder.
